COMPETING SERIES: These are the Gird and Rexburg series. Gird soils have a cambic horizon above the calcic horizon, have a maximum of 10 percent calcium carbonate equivalent in the calcic horizon. Rexburg soils have a cambic horizon above the calcic horizon and depth to the calcic horizon is 46 to 89 cm.
GEOGRAPHIC SETTING:

Landform: hills, hillslope, mountain slope, ridge, fan remnant, terrace, and lava plains
Elevation: 1402 to 2282 meters
Slope: 0 to 80 percent
Parent material: loess and silty alluvium derived from loess
Mean annual air temperature: 2.2 to 7.8 degrees C.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Rin, Tetonia, Lostine, Kucera, and Iphil soils. All of these soils occur on the same landforms. Rin and Tetonia soils have a cryic soil temperature regime. Rin soils are in swales and on north slopes, have a mollic epipedon over 40 cm thick and do not have a calcic horizon. Tetonia soils are on linear and convex positions on north slopes and have a mollic epipedon over 40 cm thick. Lostine, Kucera, and Iphil soils have a frigid soil temperature regime. Lostine soils are in swales, have a mollic epipedon over 50 cm thick and do not have a calcic horizon. Kucera soils are on hills, have a mollic epipedon over 50 cm thick and depth to the calcic horizon is 50 cm or more. Iphil soils are on eroded convex positions and are calcareous to the surface.
